But Scottish Labour Health spokesperson Jenny Marra described the memo as “concerning”.

Ms Marra said: “I have raised the issue of how prepared the NHS in Scotland was with the Health Secretary and she assured me that the government was doing everything it could and that our NHS was prepared for Ebola in Scotland.”

She continued: “It is concerning to hear that this memo had been sent out after this case and I would look for assurance from NHS 24 and all health agencies that their staff are fully briefed and fully prepared and know what to do in the event that an Ebola case self presents.”

Professor George Crooks, medical director of NHS 24, said: “NHS 24 routinely issues updated guidelines or reminders to staff in relation to service and clinical development and this has been the case case in relation to Ebola.

“On Tuesday January 6 the special helpline we had been operating in relation to Ebola closed and all such calls are now coming through the 111 number.

“Updated guidance has been issued in line with normal business.”

On Thursday Pauline Cafferkey’s family issued a statement thanking the public for their support.

“We have been very touched by the kind words,” the statement said. “Pauline continues to be in a critical condition at the Royal Free hospital.

“We want to thank all the staff caring for her for their kindness, support and compassion.

“Pauline’s condition could remain the same for some time and we would again ask for her and our privacy to be respected.”
